Have no idea, still building my basic wardrobe, almost done I think. I have prolly spent 15% of my income this past year, if I had to guess. Takes some time until you can get good at bargain hunting and knowing what to buy. I am having to try and sell the horrible fashion mistakes I made 10 months ago when I first started.
I don't plan on spending anymore than 5% this next year. Last year I really was starting from scratch. I pretty much got rid of my entire wardrobe and replaced it. $30 used to sound like a lot of money for a shirt last year. Now, I have no problem paying $100.
